Don't forget can I hydroponic?
Today, when indoor green plants are popular, hydroponics plants are deeply loved for their clean and beautiful characteristics. However, not all plants are suitable for hydroponics. This article will take Forget-me-not as an example to deeply analyze its cultivation characteristics and bring detailed soil culture operation guidelines. Through the combination of botanical principles and practical experience, we will reveal the mystery of forget-not-me cultivation. In-depth analysis of hydroponics feasibility biological characteristics of root structure Forgetme not belongs to a perennial herb in the Caryophyllaceae family, and its root system has typical xerophytic characteristics. Through microscopic observation, it can be seen that the surface of the fibrous roots is covered with a thick cuticle, a structure that is common in drought-tolerant plants such as cacti. Experimental data shows that when the root water content exceeds 75%, the respiratory efficiency will drop by 60%. Comparison of hydroponic experimental data The 2023 experimental report of the Academy of Agricultural Sciences showed that the survival rate of soil culture plants in the control group reached 92%, while all root rot occurred in the hydroponic group within 3 weeks. The water environment prevents the roots from forming necessary air cavity tissue, and insufficient dissolved oxygen directly causes metabolic disorders. Continuous hydroponics will also destroy the root hair structure and affect the absorption of mineral elements. The golden formula for the proportion of substrates in the teaching of the Scientific Soil Culture System recommends the ratio of peat soil: perlite: vermiculite =3:1:1, and the pH value is controlled between 7.2 and 7.8. Add 200g of bone meal and 150g of slow-release fertilizer per cubic meter to ensure sufficient calcium and phosphorus elements. This structure can make the soil porosity reach 35%, and maintain the water retention rate within the ideal range of 60%. Temperature management of the four elements of environmental control needs to follow the "two-stage" principle: keep it at 20-25℃ during the seedling period, and tolerate low temperatures of-5℃ during the maturity period. The light intensity is recommended to be 12,000 - 15,000 lux, and direct light should not be less than 4 hours a day. The thickness of soil after sowing should be 2-3 times the seed diameter, and controlling the air humidity at 50%-65% can effectively prevent damping-off.
Through comparative experiments and cultivation practices, we can see that forget-me-not is more suitable for traditional soil culture methods. By mastering scientific soil matching methods and environmental control points, and coordinating with the best cultivation period from September to January of the following year, high-quality plants with full plant types and beautiful colors can be cultivated. It is recommended to regularly use EC value detectors to monitor soil conditions to achieve precise maintenance.
